Profile: Jinlong Machinery is a manufacturer of ERM vibration motors. We are an ISO 9001:2008 certified company. Vibration motors generate high vibration amplitudes and are not generally not suitable for smaller devices like cellphones. These ERM motors typically require higher drive voltages than there smaller counterparts and have threaded holes behind the eccentric weight to facilitate mounting. Our vibration motors are all available with either terminal pins for connecting the cable. We can provide a cable terminated with a variety of connectors. All these high performance motors incorporate stainless steel shafts, oil impregnated bearings and precious metal brushes.
